AI Technical Summary

Benefits of technology

The invention is about improving the adjustment members of watches by using specific pivot axis geometries and magnetic pivot means. This results in better chronometric properties, especially for tourbillons or carrousels. The invention also includes a method for optimizing the chronometric properties of a mechanical watch with an adjustment member.

Problems solved by technology

Reducing the last seconds of variation in rate per day remains a very difficult objective to achieve.

Embodiment Construction

[0034]FIG. 1 shows, in a very schematic manner, a watch 1000, which includes a fixed structure 100, typically comprising a main plate and bridges.

[0035]This fixed structure 100 extends in a conventional manner substantially in a plane intended to be tangent to the user's wrist for a wristwatch, or tangent to the body or clothing of the user in the case of a pocket watch. This fixed structure 100 extends substantially perpendicularly to an axial direction D0. In most watches, this axial direction D0 is that of the axes of the display members such as hands or discs contained in a watch movement.

[0036]FIG. 1 shows only part of the adjustment member, in this case an inertia weight, which is a balance 1 here, which is returned towards a rest position by elastic return means (not represented), such as a balance spring or flexible strips. This balance 1 pivots about a balance axis D0 which is parallel here, or substantially parallel, to axial direction D0. ‘Substantially parallel’ means he...

Abstract

An adjustment member for a watch including a fixed structure extending substantially perpendicularly to an axial direction, the adjustment member including a regulating member with a balance arranged to pivot about a balance axis, this balance is pivoted by magnetic pivots in a carriage, arranged to pivot about a carriage axis, and comprised in a device for annulling variations in rate in the vertical positions, formed by a tourbillon or a carrousel, comprised in the adjustment member, and the carriage carrying magnets defining the balance axis which is perpendicular or oblique to the carriage axis.

Description

FIELD OF THE INVENTION[0001]The invention concerns an adjustment member for a watch comprising a fixed structure extending substantially perpendicularly to an axial direction, said adjustment member comprising a regulating member with a balance arranged to pivot about a balance axis.[0002]The invention also concerns a watch including such an adjustment member.[0003]The invention also concerns a method for optimising the chronometric properties of a mechanical watch comprising a fixed structure extending substantially perpendicularly to an axial direction, and comprising an adjustment member comprising a regulating member with a balance arranged to pivot about a balance axis.[0004]The invention concerns the field of adjustment members for watches.BACKGROUND OF THE INVENTION[0005]The search for better chronometric performance is a constant preoccupation of major watch companies. Essentially, this means guaranteeing a constant rate, regardless of the geometrical position of a watch in ...
